The invention relates to an air intake flow measuring method of a tubular air inlet pipe of an air compressor. The purpose that the provided measuring method has the advantages of being simple in measuring mode, precise in result and low in cost is achieved. According to the technical scheme, the air intake flow measuring method of the tubular air inlet pipe of the air compressor is characterized by comprising the following steps that 1, a measuring point A and a measuring point B are taken; 2, measurement is carried out to obtain the sectional area S1, fluid flow speed VS1 and air pressure P1 at the measuring point A and the air pressure P2 at the measuring point B; 3, the sectional area S1, the fluid flow speed VS1, the air pressure P1 and the air pressure P2 are substituted into a volume flow rate calculating formula, and the volume flow rate of an air inlet of the air compressor is obtained; 4, the sectional area S1, the fluid flow speed VS1, the air pressure P1 and the air pressure P2 are substituted int
